Speed Queen Commercial Dryer vibrating or shaking
If your dryer is vibrating or shaking during a cycle, it usually means something is stopping the drum from turning smoothly. Start with the drive motor or motor assembly—worn motor bearings often make a grinding noise and will cause vibration if the motor shaft does not turn freely. Next likely is a worn drum support bearing that lets the drum wobble, then damaged or missing felt seals that let the drum rub against the bulkhead. A stuck or worn idler pulley or idler assembly can also create vibration and a dryer making loud noise when the drum turns. Inspect each component for wear, noisy bearings, or parts that do not spin freely, and replace the faulty part to restore smooth operation. If you need the right replacement, enter your model number on RepairClinic.com to see the exact part that fits your dryer and get step-by-step guidance for the repair.
01 - Speed Queen Commercial Dryer Drive Motor
A drive motor that is wearing out will be unable to rotate the dryer drum efficiently, resulting in the dryer vibrating or shaking during operation. As the motor bearings began to wear out, the drive motor will often make a grinding noise. If the motor is noisy or the motor shaft does not turn freely by hand, the component should be replaced.

Felt seals can be found on the front or rear bulkhead of the dryer or on the front and back rims of the drum itself.

Inspect the felt seal or seals for wear or damage and replace as necessary.

05 - Speed Queen Commercial Dryer Idler Pulley
A worn or stuck idler pulley may be unable to smoothly allow the drive belt to rotate the drum efficiently, resulting in the appliance vibrating or shaking. Inspect the pulley for any wear or damage and confirm it rotates freely. If the pulley shows signs of damage or doesn't turn easily it should be replaced.
Highly Likely
